11. MANAGING AND PLAYING
ASSETS

12. Ingesting Assets from the .NET
SDK
Obtain a CloudMediaContext
• Gives you access to all objects and APIs
Create an asset (IAsset)
• A collection of media files
Create a file (IAssetFile)
• A single file within an asset
Create an access policy and locator
• Determines ACL for asset and provides a URL
for upload

13. Encoding Assets from the .NET
SDK
Obtain a media processor
(IMediaProcessor)
• Media processors can encode and package assets
Create an encoding job (IJob)
• A job is a set of tasks for Media Services
Add tasks to the job (ITask)
• E.g., encode WMV file for Apple HLS
• Tasks have input assets and output assets
Monitor job progress until it completes

14. Delivering Assets from the .NET
SDK
Locate the output asset for a job
Create an access policy and locator
Generate URLs
• For progressive download
• For streaming (IIS/HLS)
Optional: Enable CDN
• For progressive download (blob storage)
• For streaming origin server

15. Uploading and encoding an asset from the .NET SDK
DEMO

16. Playing Progressive Download
Assets
•
For progressive download in browsers
that support HTML5 video, use the
<video> element
<video width="640" height="480" controls>
<source src="@Html.Raw(Model.Mp4SourceUrl)"
type="video/mp4" />
</video>

17. Playing IIS Smooth Streaming
•
For PC and Mac delivery of IIS Smooth
Streaming, use the Silverlight Smooth
Streaming SDK
– Sample player available on CodePlex
– http://playerframework.codeplex.com/
<object data="data:application/x-silverlight-2,"
type="application/x-silverlight-2"
Server-hosted
Silverlight player
width="100%" height="100%">
<param name="source"
value="/Content/SmoothStreamingPlayer.xap"/>
<param name="InitParams"
value="mediaurl=@Model.SilverlightStreamingUrl"/>
</object>
Parameters for player

18. Playing HLS In-App on iOS
•
The iOS MediaPlayer framework natively
supports Apple HLS URLs
self.player = [[MPMoviePlayerController alloc]
initWithContentURL:[NSURL URLWithString:...]];
self.player.scalingMode = MPMovieScalingModeAspectFill;
self.player.controlStyle = MPMovieControlStyleDefault;
[self.view addSubview:self.player.view];
[self.player play];
